The EFI_RNG_PROTOCOL is needed for Linux' KASLR.
QEMU can provide a virtio-rng device to emulate a hardware random number
generator which is supported by our virtio_rng driver.
Enabling CONFIG_DM_RNG will enable CONFIG_VIRTIO_RNG and
CONFIG_EFI_RNG_PROTOCOL by default too.

Since OpenSBI commit bf3ef53bb7f5 ("firmware: Enable FW_PIC by default"),
OpenSBI runs directly at the load address without any code movement.
This causes the SPL version of QEMU 'virt' U-Boot does not boot Linux
kernel anymore. In that case, OpenSBI is loaded and runs at 0x81000000,
and it creates a 512KiB PMP window from that address. When booting
the Linux kernel, moving kernel to its linking address 0x80200000
overlaps the PMP window, and a PMP access failure is raised.
Update SPL_OPENSBI_LOAD_ADDR to load OpenSBI to a safe address.

Add two new configurations (qemu-riscv{32,64}_spl_defconfig) with SPL
enabled for RISC-V QEMU. QEMU does not require SPL to run U-Boot. The
configurations are meant to help the development of SPL on RISC-V.
The configurations enable RAM as the only SPL boot device. Images must
be loaded at address 0x80200000. In the default boot flow, U-Boot SPL
starts in machine mode, loads the OpenSBI FW_DYNAMIC firmware and U-Boot
proper from the supplied FIT image, and starts OpenSBI. U-Boot proper is
then started in supervisor mode by OpenSBI.

in S-mode whereas for 64bit system it will jump to 0x80200000 address
in S-mode.
Currently, the S-mode U-Boot sets SYS_TEXT_BASE to 0x80200000 for both
32bit and 64bit system. This breaks S-mode U-Boot for 32bit system.
This patch sets different SYS_TEXT_BASE for 32bit and 64bit system so

When u-boot runs in S-mode, the M-mode runtime firmware
(BBL or equivalent) uses memory range in 0x80000000 to
0x80200000. Due to this, we cannot use 0x80000000 as
SYS_TEXT_BASE when running in S-mode. Instead for S-mode,
we use 0x80200000 as SYS_TEXT_BASE.
Even Linux RISC-V kernel ignores/reserves memory range
0x80000000 to 0x80200000 because it runs in S-mode.

QEMU specifies the location of Linux (supplied with the -kernel
argument) in the device tree using the riscv,kernel-start and
riscv,kernel-end properties. We currently rely on the SBI implementation
of BBL to run Linux and therefore embed Linux as payload in BBL. This
causes an issue, because BBL detects the kernel properties in the device
tree and ignores the Linux payload as a result.
Work around this issue by clearing the kernel properties in the device
tree before booting Linux.

software. It implements RISC-V privileged architecture spec v1.10.
Both 32-bit and 64-bit builds are supported. Support is pretty much
